“Ritz Theater began life as the Gem Theater and was operated by Mr. and Mrs. Charlie Greever. The Gem featured a stage in front of the screen and featured interesting acts such as man vs. kangaroo boxing matches, a veteran of the Great War that had been gassed by the Germans, and entertainment legends such as Gene Autry and Smily Burnett. The theater featured both piano and organ music and delighted children with Lassie, Hopalong Cassidy, and Roy Rogers. On a more comical note, the Ritz was known for its very poor bathroom facility. Between serials, patrons would dash out of the theater to the nearby Sinclair gas station for relief. The Ritz was also kept exceptionally dark to help the brightness of the picture on the screen. The Ritz closed in the 1950s.”
